Abstract

The clutting device (1) for an extruder (10) has a drive (2) and a tensioned cutting wire (3) on a movable mount (4) with which the cross-sectional surface (12) of the extrudate (11) can be swept over by the cutting wire (3). The wire is moved by the mount such that, during the cutting through of the extrudate, it has an axial velocity component V1 in the direction of its axis and a velocity component V2 orthogonal thereto. The thin, rapidly moved cutting wire consists of high-strength material. Using the cutting device, even hollow extrudates can be cut precisely to the desired final shape without any need for finishing. <IMAGE>
